Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20140723)

It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially...

Linux Kernel l2tp_ip_sendmsg()和pppol2tp_sendmsg()函数整数溢出漏洞

BUGTRAQ ID: 44762 CVE ID: CVE-2010-4160 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel中的PPPoL2TP实现（net/l2tp/l2tpppp.c，pppol2tpsendmsg）和IPoL2TP实现（net /l2tp/l2tpip.c，l2tpipsendmsg）都调用了sockwmalloc，而后者没有执行任何边界检查便对大小参数执行了算术运算。因此，如果发布了超大大小的sendto调用，这个分配大小就会回绕，导致分配过小的缓冲区。成功利用这个漏洞可能导致内核忙碌或内核堆溢出。 Linux...
